Question  Answer 
efficiency  useful output/total input 
gravitational potential energy (2)  weight x height mass x gravity x height 
kinetic energy  1/2 x mass x velocity"2" 
weight (2)  mass x gravity (10) density x volume x 10 
speed (2)  distance/time frequency x wavelength 
frequency  1/time period 
force on a spring  spring constant x extension 
water pressure  10 x depth x density 
upthrust  weight of water displaced 
current  charge/time 
voltage  energy/charge 
resistance  voltage/charge 
pressure  force/area 
stopping distance  braking distance + thinking distance 
power (3)  current"2" x resistance energy/time current x voltage 
acceleration  change in velocity/time 
force  mass x acceleration 
work done  force x distance 
apparent weight  true weight  upthrust 
equation of motion  final velocity"2" = initial velocity"2" + 2 x (10 forward 10 backward) x distance
